Metallurgy - Panoramic Resources

SAG mill comminution (SMC) testing showed the Savannah North mineralisation to be "very soft" to "soft". The softer comminution parameters will provide some scope to either maintain mill throughput while producing a finer grind P 80 or alternatively maintain the existing grind P 80 at a slightly higher mill throughput.

What's the Difference Between SAG Mill and Ball Mill ...

The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...

Ball Mills - Mineral Processing & Metallurgy

In all ore dressing and milling Operations, including flotation, cyanidation, gravity concentration, and amalgamation, the Working Principle is to crush and grind, often with rob mill or ball mill, the ore in order to liberate the minerals. In the chemical and process industries, grinding is an important step in preparing raw materials for subsequent treatment.

Crushing in Mineral Processing

In mineral processing or metallurgy, the first stage of comminution is crushing.. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear-resistant plate/surface.

Nickel | BHP

Nickel is a silvery white, naturally occurring metallic element with a light golden tinge. There are two main types of nickel deposits - laterite and sulphide – each requiring a different extraction technique. Stainless steel. Nickel sulphide and laterite ore are used to make nickel metal, predominantly for the production of stainless steel.

A SAG mill of diameter 9.0 m and width 6.0 m was charged to 40% of the mill volume with ore of SG 3.2 when the porosity was 38%. With grinding time the ball load changed from 10% to 5% and the bed porosity to 12%. Estimate the change in power due to the change in mill conditions. The mill was run continuously at 70% of the critical speed.
